A cost-effective system provides reliable location information for locating a vehicle tied to a guideway. Reference markers are mounted to the guideway and scanning devices are disposed in the vehicle and generate at least one output signal when they pass a reference marker. The scanning devices are formed from several individual sensors which are extended in the driving direction with an average scanning length equal to or greater than a distance between neighboring reference markers.

The invention claimed is: 1. A system for locating a vehicle tied to a guideway, comprising:a plurality of reference markers disposed on the guideway at a given spacing distance along the guideway;a scanning device mounted to the vehicle and generating an output signal when said scanning device passes a reference marker as the vehicle travels along the guideway;said scanning device having a plurality of individual sensors and extending in a direction of travel with an average scanning length, the average scanning length being equal to or greater than the given spacing distance between mutually adjacent said reference markers;said individual sensors disposed next to one another being configured to generate output signals with mutually different signs as said individual sensors travel over a reference marker;said individual sensors being disposed in two rows of sensors next to one another and extend in the direction of travel;said two rows of sensors being disposed with an offset relative to one another in the direction of travel;said offset being equal to half a dimension of said reference markers in the direction of travel; andsaid scanning device being configured to continuously read said plurality of reference markers located along the guideway.
